Disclosed are an air cooler, a cooling system thereof and a temperature regulating and balancing method for a CT scanning machine. The air cooler includes a condenser (4); a plurality of negative pressure fans (6) are provided in an array on the back side of the condenser (4); a condensed water tank (7) is arranged below the condenser (4); a water pump (8) is provided in the condensed water tank (7); a porous spraying pipe (14) is provided at the upper end of the condenser (4); and the porous spraying pipe (14) is connected to the water pump (8) through a pipeline. The cooling system comprises a CT scanning machine (101), an auxiliary air cooler (B) and a main air cooler (A) in parallel, a receiving controller (107), a transmitting processor (108), a bulb tube temperature sensor (109), a condenser temperature sensor (110), a detector temperature sensor (114) and a displacement sensor (111). A cold air outlet (11) of the auxiliary air cooler (B) is connected to the main air cooler (A) through a connector (118) and is connected in parallel to a cold air outlet (11) of the main air cooler (A), and the cold air outlet of the auxiliary air cooler and the cold air outlet of the main air cooler are jointly in communication with an air inlet (105) of a rack through a cold air pipeline (113). According to the invention, no condensed water is stored in the air coolers, so that the energy efficiency of refrigeration is improved; the cooling system directly cools a CT scanning rack, so that air temperatures of the CT bulb tube and a detector assembly in the scanning rack are reduced. |
